Polydisperse sphere packing with various size distributions.

Fields

distribution: SizeDistribution

Distribution type.

params: SizeDistributionParams

Distribution parameters.

domain: [f64; 3]

Domain dimensions.

spheres: Vec<PackingSphere>

Placed spheres.

max_attempts: usize

Maximum placement attempts.

Implementations

impl PolyDispersePacking

pub fn new( distribution: SizeDistribution, params: SizeDistributionParams, domain: [f64; 3], max_attempts: usize, ) -> Self

Create a new polydisperse packing.

pub fn sample_radius(&self, rng: &mut impl Rng) -> f64

Sample a radius from the configured distribution.

pub fn is_valid_placement(&self, center: [f64; 3], radius: f64) -> bool

Check if a sphere with given center and radius can be placed.

pub fn run(&mut self, n_spheres: usize) -> usize

Run RSA with polydisperse radii.

Returns the number of spheres placed.

pub fn packing_fraction(&self) -> f64

Compute the packing fraction.

pub fn radius_statistics(&self) -> (f64, f64, f64, f64)

Return radius statistics: (mean, std, min, max).

pub fn polydispersity_index(&self) -> f64

Compute the polydispersity index (PDI): std/mean.

pub fn size_histogram(&self, n_bins: usize) -> (Vec<f64>, Vec<usize>)

Compute the size distribution histogram.

Returns (bin_centers, counts).
